预装式变电站在分布式光伏的应用

Application of Preinstalled Substation in Distributed Photovoltaic

预装式变电站属于一种新型的变电设备,由于其具备运行可靠性较高、便于维护和管理、造型美观、安装周期短、安装流程简单等特点,在工厂内模块化集成调试后,运达施工现场,少量场区接线既可投入运行,减少了建设工期和土地。本文介绍了分布式光伏电站建设现状及组成,分析了预装式变电站建设特点,结合工程实例,阐述了变电站三个模块预制舱的结构、电气设计布置方案。

Preinstalled type substation belongs to a new type of substation equipment,due to its high reliability,easy to maintain and manage,beautiful modelling,short installation period,simple installation process and so on,modular integration within the plant after debugging,to the construction site,a small amount of ground connection can be put into operation,reduce the construction time limit for a project and the earth.This paper introduces the construction status and composition of distributed photovoltaic power station,analyzes the construction characteristics of pre-installed substation,and expounds the structure and electrical design layout scheme of the three modules prefabricated modules of substation combined with engineering examples.
